Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this investigation was to describe the characteristics on the debonded interface of the Transcend Series 2000 ceramic bracket. Thirty patients were selected by convenience from the University of Missouri-Kansas City, School of Dentistry, Department of Orthodontics. The maxillary anterior teeth were bonded using Transcend Series 2000 ceramic brackets, Transbond adhesive, and a Unitek 37% phosphoric acid etching solution. The teeth were etched for fifteen seconds as recommended by the manufacturer. After four months of wear the brackets were removed and assessed. One bracket was randomly selected from each patient and was studied using scanning electron micrographs and analyzed with the EDAX instrumentation. A correlation was used to validate the use of a new grid method for assessing the remaining resin. The quality analysis of residue, on the base of the brackets, was made with the EDAX instrumentation. The results showed that the fracture site was predominantly at the bracket-resin interface. The results showed that the Transcend Series 2000 ceramic brackets were safe to use clinically, as they did not remove significant amounts of enamel upon debonding.

Book excerpt: This book was authored to cater for all aspects of orthodontic brackets. The focus being to provide students with real time pictures of different brackets available in the market and to determine their behaviour in oral cavity and their appearance after debonding. The main emphasis being on three vital aspects viz; the selection, placement and debonding, this book has accordingly been designed to comprise these three sections. Real times of new and used brackets have been specifically included to provide the students a realistic insight of brackets.Care has been taken to ensure correlation of clinical situation and various bracket selection criterion

This book was released on 2019 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: This study evaluated the effect of primer protocol for metal orthodontic brackets bonded to zirconia ceramic and resulting shear bond strength (SBS), adhesive remnant index (ARI), and debonded and polished zirconia surface roughness. Methods: Zirconia specimens were milled, glazed, embedded in acrylic resin and the target area microetched with aluminum oxide. Glazed and microetched representative specimens were evaluated with energy dispersive spectroscopy (EDS). Specimens were randomly assigned to primer protocol, enamel (TransbondTM Plus Self-Etching Primer) or zirconia (Assure® Plus), and primed according to manufacturer instructions. Metal orthodontic brackets were bonded to the primed surface with resin adhesive (Transbond XTTM) and light cured. To simulate intraoral conditions, all primer and bonding protocols took place in an environmental chamber set at 33±2°C and 75±5% humidity followed by a 24-hour dark cure at 37 C. Following SBS testing, an ARI value was assigned to debonded brackets. Residual adhesive was removed from the debonded zirconia specimens, the zirconia surface polished, and surface roughness measured using a profilometer. Scanning electron microscopy (SEM) was performed for qualitative evaluation of the zirconia surface. Results: Zirconia substructure exposure by aluminum oxide microetching was verified with EDS. A significantly lower (p

Available in PDF, EPUB and Kindle. Book excerpt: AIM: 1. To determine in vitro bond strength of metal and ceramic orthodontic brackets when using etch and separate primer, or self-etching primer (SEP) 2. To assess remaining adhesive following removal of orthodontic bracket METHOD: 180 previously extracted teeth were randomly allocated to one of six test groups. Each was subjected to either separate etch and primer or SEP and then bonded with an orthodontic bracket. These were metal (3M Unitek Victory), metal reinforced ceramic (3M Unitek Clarity) and poly-crystalline ceramic (3M Unitek Transcend). Samples were stored at 37 degrees C for 24 hours. Each bracket was debonded using shear force applied by the Instron Universal testing machine. Samples were examined under x10 light microscopy and allocated an Adhesive Remnant Index (ARI) score. RESULTS: Variation in shear bond strength (SBS) was seen across all groups. Lowest SBS was recorded with Victory series brackets bonded with SEP (7.08 MPa) and the highest was with Clarity series brackets bonded with separate etch and primer (15.96 MPa). Pooled data showed significantly higher SBS with separate etch and primer than SEP (T=2.83, p

Download or read book Comparing Two Orthodontic Brackets Bond to Fluorosed and Non fluorosed Enamel written by Serufe Emily Monehi and published by . This book was released on 2014 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orthodontic attachments must be able to bond to a wide range of tooth and prosthetic surfaces. Despite the high prevalence of fluorosis in many parts of South Africa (Louw A, Chikte U 1997), only limited information is available on the integrity of the bond between orthodontic brackets and fluorosed teeth. The objective of this study was to measure and compare Shear Bond Strengths (SBSs) of metal and ceramic orthodontic brackets on fluorosed and non-fluorosed teeth. One hundred and twenty (60 fluorosed and 60 non-fluorosed) extracted premolar teeth were divided into four groups A to D, consisting of 30 teeth in each group. BluGloo® was used as an orthodontic adhesive to bond brackets on the buccal surface of each tooth. The experimental groups consisted of Group A, in which Nu-Edge® metal brackets were used and Group B, in which InspireIce® ceramic brackets were bonded to fluorosed teeth. Group C and D consisted of Nu-Edge® metal brackets and InspireIce® ceramic respectively, bonded to non-fluorosed teeth. Bonding techniques were kept the same and standardised for all four groups. An Instron testing device was used to debond and measure the SBSs. SBSs were compared using ANOVA with posthoc analysis done using Dunnett’s C test for pairwise comparisons. Significance was set at P0.05. The results showed that SBS of Group BGroup C>Group D>Group A. Ceramic brackets bonded to fluorosed teeth had the highest SBS with a mean of 15.78 (SD=9.07) Megapascals (MPa), while metal brackets bonded to fluorosed teeth produced the lowest SBS of 8.41 (SD=4.68) MPa. The SBSs of ceramic brackets bonded to fluorosed teeth was significantly higher than that of SBS of metal brackets bonded to fluorosed teeth, but not significantly different from SBSs obtained from either brackets bonded to non-flurosed teeth. The BluGloo adhesive if used to bond ceramic brackets to fluorosed teeth can produce adequate SBS for clinical use. The recommendation from this study is that ceramic brackets can be used efficiently to bond to fluorosed teeth. A follow up study should be carried out to assess the nature of enamel damage caused during debonding of flourosed teeth. This is a laboratory study and thus the clinical application should be interpreted with caution.
